Answer 1

1)

$|2 - 3x| = 0 \\ 2 - 3x = 0 \\ - 3x = - 2 \\ x = \frac{2}{3}$

2)

$|4 - 5x| = 0 \\ 4 - 5x = 0 \\ - 5x = - 4 \\ x = \frac{4}{5 } \\ x = 0.8$

3)

$|3x + 1| + {2}^{3} = 8 \\ |3x + 1 + 8 = 8 \\ |3x + 1| = 0 \\ 3x + 1 = 0 \\ 3x = - 1 \\ x = - \frac{1}{3}$

4)

$|9x + 2| - {3}^{3} = {( - 3)}^{3} \\ |9x + 2| - 27 = - 27 \\ |9x + 2| =0 \\ 9x + 2 = 0 \\ 9x = - 2 \\ x = - \frac{2}{9}$
